5x - (x - 16) = 2x - (_) + x)

          x=1

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation   16-2*x-(5*x+9)=0

Pull out like factors :   7 - 7x  =   -7 • (x - 1)

Solve :    -7   =  0  This equation has no solution.

A a non-zero constant never equals zero.

Solve  :    x-1 = 0    Add  1  to both sides of the equation :  

                     x = 1

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
